概要	Noise mapping is an environmental assessment methodology that quantifies and visualizes sound levels spatially across a study area, enabling identification of noise-exposed populations, compliance with regulatory standards, and design of mitigation measures. Standardized by the European Directive 2002/49/EC and ISO 13442, noise mapping combines acoustic measurements, traffic/industrial source modeling, and geographic information systems (GIS) to create contour maps of sound exposure and associated health impacts.	Air dispersion modeling is a quantitative method to predict the concentration and deposition of air pollutants (dust, gases, particulates) released from industrial sources, traffic, or combustion. Developed empirically by Pasquill and Gifford in the 1960s and formalized into the Gaussian plume model, these methods predict ground-level concentration downwind of a source using wind speed, stability class, source height, and meteorological data. Air dispersion models are essential tools for regulatory compliance, emission permitting, and exposure assessment.
